BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to wooden bats that are used to play baseball, softball, or other games that require a player to strike a pitched ball with a round wooden stick. The invention related more specifically to a mass distributive wooden bat wherein the mass of the bat barrel is evenly distributed between the distal end and proximal end of the bat barrel, creating a larger effective hitting zone and sweet spot that is more forgiving of miss hits.

2. Description of Related Art

A traditional baseball bat is a smooth, round stick continuously tapered along its longitudinal axis. The barrel is the thick part of the bat, where the bat is meant to hit the ball. The barrel narrows, and becomes the handle. The handle is the area where the bat is held by the player's hands and used to swing the bat and terminates in a knob that helps prevent the bat from slipping through the player's hands. The part of the barrel best for hitting the ball is often called the sweet spot. From a player's viewpoint, the sweet spot is the place on the bat barrel where the contact between bat and ball results in the best hit—the ball leaves the bat with the greatest speed and the player's hands feel very little vibration from the impact.

A baseball batter will have the best probability of hitting a pitched baseball if they can swing a bat of a maximum diameter permitted by league regulations, quickly enough to hit the incoming high-velocity pitched baseball. However, a bat of maximum diameter usually means a slower swing speed due to heavy weight of a wide diameter bat. Typically, the sweet spot of a traditional baseball bat is rather small and miss hits do not rebound off the bat sharply. Therefore, there has been a need to come up with a baseball bat that provides high swing speed and larger sweet spot.

Efforts have been made to provide baseball bats that satisfy the aforementioned needs, for example, a baseball bat design with ball hitting portions of non-circular cross section as is shown in the expired U.S. Pat. No. 400,354 to Morris; a baseball bat having hitting portion with a square transverse cross section as is disclosed in U.S. Pat. No. 3,104,876 to Salsinger; a hollow bat having a ball hitting portion with three striking surfaces as is disclosed in U.S. Pat. No. 3,880,423 to Kreag; and a baseball bat having a transverse cross section periphery that is divided into two dissimilar half segments as is shown in U.S. Pat. No. 4,331,330 to Worst. Other efforts were made to optimize the power zones by weighting the bats between the impact (hitting zones) and the knob end as is disclosed in U.S. Pat. No. 4,834,370 to Noble et al. U.S. PreGrant Pub. No. 20090011877 discloses a bat for baseball or softball that includes a core member having a depression at a portion to be a ball-hitting portion, and an elastic body attached to the depression and forming the ball-hitting portion. According to major league baseball bat rule 1.10(a), the baseball bat should be a smooth, round stick not more than 2.75 inches in diameter at the thickest part and not more than 42 inches in length. The bat shall be one piece of solid wood. Therefore, the aforementioned patents and publication are not compliant with the regulation. U.S. PreGrant Pub. No. US 2002/0016230 to Okuyama et al. discloses a baseball bat including an impact portion which has a smaller diameter at a sweet spot than at the other portions of the impact portion, and which has a recessed external shape in the longitudinal direction. Because the diameter of the impact portion starts to decrease from the distal end of the bat until reaching the sweet spot and then starts to increase until it returns to the original size at the end of the impact portion, the sloping surface around the sweet spot makes it difficult to control the striking direction.

Therefore, there is still a need to have a baseball bat that can provide batters higher probability of hitting the ball on the sweet spot while maintaining high swing speed and meeting the major league baseball bat requirement.

SUMMARY OF THE INVENTION

The need to have a baseball bat that can provide batters higher probability of hitting the ball on the sweet spot while maintaining high swing speed is achieved according to the principle of the present invention solely by redistributing the mass of the bat along the bat barrel without artificial or outside weighting. The mass distributive baseball bat of the present invention meets the major league baseball bat requirement.

An object is to provide a mass distributive design baseball bat that distributes the mass of the bat between the distal end of barrel and the proximal end of barrel thus enlarging the sweet spot.

Another object is to provide a mass distributive design baseball bat that expands the sweet spot making a pitched ball more likely to be sharply struck thus increasing the chances of a base hit.

Another object is to provide a mass distributive design baseball bat that distributes the mass in such a way that even if a pitched ball does not strike on the sweet spot, it will still be struck more sharply than a traditional baseball bat design, thus increasing the likelihood of a base hit.

Another object is to provide a mass distributive design baseball bat that shall meet the major league baseball bat requirement; the baseball bat of the present invention should be a smooth, one piece of solid wood, round stick not more than 2.75 inches in diameter at the thickest part and not more than 42 inches in length.

The invention generally relates to a wooden baseball bat which includes taking the general shape of a traditional baseball bat that typically is of a tapering design where the thickest portion is near the distal portion of the bat with varying degrees of taper toward the handle and redistributing the mass such that there is a thicker area more toward the handle while leaving the diameter of the effective hitting zone and distal portion of the bat approximately the same as that of a traditional baseball bat.

A traditional wooden baseball bat is of round design with a near continuous taper from the thickest portion of the barrel to the handle. Because of its design, the effective hitting zone, i.e. the area of the bat where a pitched ball will be sharply struck, is relatively small, measuring just an inch or two distally or proximally from the sweet spot. The mass distributive design baseball bat comprises a distal end that is no more than 2.75 inches in diameter followed by a more proximal effective hitting zone of a narrower diameter, followed more proximally by a thicker section no more than 2.75 inches in diameter, followed more proximately by a tapered barrel end, followed more proximally by a traditional baseball bat handle. The overall mass of the bat remains approximately the same as a traditional continuously tapered baseball bat and the diameter of the sweet spot remains approximately the same as a traditional baseball bat but the mass is more evenly distributed proximally to distally along the barrel of the bat making a larger effective hitting zone. In the preferred embodiment, the effective hitting zone is about 6 inches in length and about 2.13-2.25 inches in diameter.

The design goals are achieved solely by redistributing the mass of the bat without artificial or outside weighting. The bat may further comprise an indentation in the distal end of the bat up to one inch in depth and may be no wider than two inches and no less than one inch in diameter. The indentation should be curved with no foreign substance added.

The manufacturing process to produce the mass distributive design bat is of traditional construction techniques utilizing a lathe and/or cutting heads to produce a wooden bat designed to be used to strike a pitched ball. It may be made of ash, maple, and/or other wood material known in the art.

The exact dimensions of the mass distributive design bat can be varied to meet the preferences of individual players while maintaining the basic design concept of a thicker more massive distal barrel followed proximally, by a thinner effective hitting zone, followed by a thicker more massive proximal barrel, followed proximally by a tapered barrel end, followed proximally by a thinner traditional handle terminating in a small thicker knob. The shape of the knob can be varied to meet individual batter preferences. The same design concepts apply to a wooden bat that would be used to play baseball, softball, or other games that requires a player to strike a pitched ball with a round wooden stick. The preferred embodiment mentioned in the present application relates to adult baseball bats, the dimension (i.e. length and diameter) and mass distribution of the bat shall be adjusted for youth baseball bat or softball bat.

The best use of the mass distributive design baseball bat is to strike a pitched ball. Its design is such that the mass is distributed more evenly across the effective hitting zone allowing a larger effective hitting area than a traditional baseball bat. The effective hitting area of a traditional baseball bat is rather small and miss hits do not rebound off the bat sharply. The mass distributive design creates a larger sweet spot, thus increasing the rebound of a miss hit baseball. This is accomplished by having a larger diameter at the distal barrel followed by a smaller diameter effective hitting zone followed by a larger diameter proximal barrel mass creating a larger sweet spot for allowing miss hits to be more sharply struck while maintaining the overall weight and feel of a traditional baseball bat. The bat is used the same as a traditional baseball bat with the batter grasping the bat handle with his hands and attempts to hit a pitched ball. Like a traditional bat there is a knob at the end that helps prevent the bat from slipping out of the batters hands.

DESCRIPTION OF THE PREFERRED EMBODIMENT

A traditional baseball bat 1 is a smooth, round stick continuously tapered along its longitudinal axis as shown in FIG. 1. The barrel 10 is the thick part of the bat, where the bat is meant to hit the ball. The barrel narrows, and becomes the handle 15. The handle 15 is the area where the bat is held by the player's hands and used to swing the bat and terminates in a knob 16 that helps prevent the bat 1 from slipping through the player's hands. The part of the barrel 10 best for hitting the ball is often called the sweet spot 121.

Referring to FIG. 2, there is disclosed a preferred embodiment of a mass distributive design baseball bat 1 according to the present invention.

The mass distributive design bat is a round solid wood bat with a distal end mass 11 that is no more than 2.75 inches in diameter followed by a more proximal effective hitting zone 12 of narrower diameter, followed more proximally by a thicker proximal barrel mass 13 of no more than 2.75 inches in diameter, followed more proximally by a tapered barrel end 14, followed more proximally by a traditional baseball bat handle 15, and finally followed by a knob 16 at the proximal end of the bat 1. The overall mass of the bat 1 remains approximately the same as a traditional continuously tapered bat and the diameter of the sweet spot 121 remains approximately the same as a traditional bat but the mass is more evenly distributed between the distal barrel mass 11 and proximal barrel mass 13 along the barrel 10 of the bat 1 making a larger sweet spot 121.

In the preferred embodiment, the distal barrel mass 11 comprises a most distal end 111 with an increasing diameter from about 2.13-2.25 inches to about 2.63-2.75 inches across its length of about 0.75 inch, a proximal section 112 that has a uniform diameter of about 2.63-2.75 inches through its entire length of about 1.5 inches, and a more proximal section 113 that has a diameter decreasing from about 2.63-2.75 inches to about 2.13-2.25 inches across its length of about 1 inch. The effective hitting zone 12 following the section 113 has a uniform diameter of about 2.13-2.25 inches through its entire length of about 6 inches. According to the present invention, the diameter of the sweet spot 121 is same as traditional bat but mass is more evenly distributed between the distal barrel mass 11 and the proximal barrel mass 13 along the effective hitting zone 12, creating a larger sweet spot 121 that is more forgiving of miss hits. The proximal barrel mass 13 follows the proximal end of the effective hitting zone 12 comprises two sections. The first section 131 has a diameter increasing from about 2.13-2.25 inches to about 2.63-2.75 inches across its length of about 1 inch; the second section 132 has a uniform diameter of about 2.63-2.75 inches throughout the entire length of about 2.25 inches. The barrel end 14 following the proximal end of the proximal barrel mass 13 starts to taper until the diameter reaches about 0.94-1.0 inch where the handle 15 starts. The diameter of the handle 15 is then maintained uniformly (about 0.94-1.0 inch) throughout the entire length of no more than 18 inches. The handle 15 is the area where the bat is held by the player's hands and used to swing the bat and terminates in a knob 16 that has a diameter of about 1.75 inch to help prevent the bat from slipping through the player's hands.

The handle 15 may be wrapped with a rubber or cloth grip. The barrel 11 may further comprise a cup end 114 at the most distal end of the bat 1; the dimension of the cup end 114 may be varied as required for weight adjustment. The cup end 114 is no more than one inch in depth and no more than 2 inch wide and no less than one inch in diameter. The cup end 114 is curved with no foreign substance added. The preferred baseball bat 1 of the present invention is about 34 inches long; the target mass of the bat is about 31 ounces.

The exact dimensions of the mass distributive design bat 1 can be varied to meet the preferences of individual players while maintaining the basic design concept of a thicker more massive distal barrel mass 11, followed proximally by a thinner effective hitting zone 12, followed proximally by a thicker more massive proximal barrel mass 13, followed proximally by a tapered barrel end 14, followed proximally by a thinner more traditional handle 15 terminating in a small thicker knob 16. The shape of the knob 16 can be varied to meet individual batter preferences. The same design concepts apply to a wooden bat that would be used to play baseball, softball, or other games that requires a player to strike a pitched ball with a round wooden stick.

The manufacturing process to produce the mass distributive design bat 1 is of traditional construction techniques utilizing a lathe and/or cutting heads to produce a wooden bat designed to be used to strike a pitched ball.

FIG. 3 is a cross-sectional view taken along the line A-A of the embodiment disclosed in FIG. 2 showing that the mass distributive design baseball bat of the present invention is a round solid bat.
